l SEEDING-rinomate.

To all whom t may concern.' Be it known that I, HUGH W. THOMAS- sorua citizen of the United States of America, a resident of the city of St. Louis, State of Missouri, vhave invented certain new and useful Improvements in Seeding-Machines,

of which the following is a full, clear, and

exact description, reference'being had to the fio accompanying drawings, forming apart of this specification. 7

My invention relates to a` seeding machine of the kind which lmay be 'termed broadcast seede'rs, the invention having for its object to provide a machine of this kind ofl lsimple andk inexpensive construction which may be utilized -inv thevsowing of either small or large seeds, and through the mediumy of which seeds may be scattered l uniformly overthe surface of the ground in- Fig. I. In thedrawing's, 1 designatesv'a vmain seed l so vso

tended to receive them. f y `Figure I is a rear elevation of myvseeding machine with thezcentra'lportion of the machine broken out. y

hopper which may be'supported in any suitable mannerzby ground wheelsV (notfshown). The hopper is provided at its bottom'with a discharge'throat :2 through which-the seed to ,be planted escapes, and at each end'ofl when the machine is utilized for sowing4 small seeds, which will readily pass through the narrow slot-5.

6 designates an upper feedingl cylinderextending longitudinally in the mainhopper 1 beneath the subhopper 4, said cylinder beingy arranged t0 revolve in contact wlth ythe bottom of the sub feed hopper and having llongitudinal pockets y7 therein, which .receive the seed-as it passes through the slot in the subhopper rand discharges such seed so that it may'descend through the discharge Specification of Letters Patent.

throat '2 of the main hopper. The upper feed cvlinder 6 has shaft extensions 6 extending exteriorly ofthe main hopper '1, said shaft extensions having wheels 8 fixed thereto and being provided with means whereby they may be driven, the means shown for this purpose comprising sprocket wheels 9 having sprocket .chains 10 itted thereto, which serve to convey power fro-m some rotating part of the seeding machine, for example, its axle. r

1l Adesignates a lower feed cylinder extending longitudinally between the support ing wings 3 and therefore longitudinally Vof the main hopper'l beneath its discharge throat 2.V This lower feed cylinder `is grooved, .or 'luted, providing longitudinal pockets 1l',` and is provided with shaft extensions 12 mounted yin .the supporting 'wings 3, said shaft extensions having fixed thereto driving wheels 13 arranged in mesh with the `wheels 8 on the shaft extensions of the upper' feed cylinder 6.

14 designates a curved runway plate, exs tending downwardly from the rear wall of the main` hopper 1 and on which the seedy discharged through the youtlet throat of the main hopper descends to become deposit# ed in the longitudinal pockets in the lower feed cylinder 1l,.the lower edge .of said memberlt being so'disposed that the ridges of saidfeed cylinder will move in close proximity thereto, as indicated in Fig. II. A curved wiper plate 15 arranged parallel with the runway plate 14- has its upper portion pivotally tted at 16 tothe supporting wings 3 and its lower free edge rests idly upon the lower feed cylinder so that said wiper plate may vibrate duringrotation of thel lower feeding cylinder `and perform a wiping action with respect to each pocket in the feeding cylinder, in order that only a predetermined quantity of seed will be carl 'ried by each pocketof said cylinder after deposit therein from the passagewaybetween the members 14 and 15. 17 designates a curved seed distributing plate located in front of and extending rearwardly beneath the lower feed cylinder 11.

f This seed distributingplate has a wavelike rear free edge which lies in close proximity to the periphery of the lower feed,

studs 18 disposed in inclined slots 19 extending downwardly and rearwardly from the 'cylinder and said plate is supported by pivot.`

front edg'eso'fV thef supportingrm wings 3 to wardthe axis of the feed cylinder Il.V '.Il're'"4 'upper portion of thefeed-distributingplate 17 isl weighted, as seen in Fig. II, tol provide I f ery ofv small seedto thelower feedvcylinde'r 11. 'Whenlarger seeds 1 are tov be.lsown,-the subhopper 4 isremoved from the; main' hop:-

as-indi'cated-by the arrows, Figs II andIIL Ilf theseeds are'small the wiper platey 15 performs a wiping action'a'cross the; longitu-v dinal pockets-in the lower'feed cylinder, with the 'r'esultjthat each pocketcarries 'onlyfsuf-jticient seedxto fill lit-as "it, passeszbeyond the;k

wiper 1; late,"`^and this seedlfis then carried in the pocket whileI the latteris traversing the: distributing platefl7preparat'ory to the dis-, charge ofthe ,seed onto the ground. If'v larger seedsare being' sown,some of them; projects from the pockets .inv the lower. cylinder, and `the wiper plate .15, being-pivotally mounted, moves upwardly to permit the passage of the :filled pocket beneath the lowerA edge ofthe 4wiper plate, and as the pocketsso fill/ed reach the distributing plate I7 `the seedthe'reinlf presses againstthedis-l tributing plate, forcing thel latter ,slightly away fromfthesperiphery ofjthe lower feedcylindersv The'movement of the distri-butlimitr'myself to its being of Asaid shape.`

The distributing plate 17, having a wave-2 'lile'freey edge, provides for the seed in the Vlongitudinal pockets of Lthe lower feed cylinder' being welly scattered onto the ground y instead of falling thereto in .a straight stream,*as would be the case ifthe edge ofsaid distributing plate were straight.
